Backflow Testing & Certification Services in Columbus, Ohio

Certified Backflow Testing to Protect Your Water Supply

Backflow testing is a mandatory annual requirement to ensure that your drinking water remains safe from contamination. If your backflow prevention device hasn’t been tested or certified, you risk water shutoff by local authorities.

At The Waterworks, we provide certified backflow testing, certification, and repairs for homeowners, businesses, and municipal facilities across Columbus and Central Ohio. Our team ensures that your backflow preventers comply with all local and federal regulations, keeping your water supply safe and contaminant-free.

Call us today to schedule your annual backflow testing and stay in compliance!

What Are the Legal Requirements for Backflow Testing?

Federal and Ohio state laws require that all backflow prevention devices be tested annually by a certified backflow tester. These regulations help prevent contaminants, pesticides, and chemicals from entering the drinking water supply.

If your backflow device is not tested, local authorities may shut off your water supply. Each device has a unique serial number for tracking, and all testing and repairs must be completed by the property owner.

At The Waterworks, we make the process easy and hassle-free by handling:

  • Certified backflow testing
  • Official documentation & compliance reporting
  • Backflow device repairs and replacements (if needed)

We provide same-day testing and repairs, so you can stay compliant and keep your water safe.   

Why Is Backflow Testing Important?

Backflow prevention devices protect public and private water supplies from contamination caused by:

  • Pesticides & Fertilizers from irrigation systems
  • Chemicals & Industrial Waste from businesses and manufacturing facilities
  • Sewage & Wastewater from damaged plumbing lines
  • Fire Suppression Systems that can allow stagnant water to enter drinking supplies

Benefits of Annual Backflow Testing

  • Protects your home or business from water contamination
  • Prevents serious health risks from chemicals & bacteria
  • Ensures compliance with Ohio state and federal regulations
  • Avoids costly fines or water shutoffs

If you have a sprinkler system, irrigation system, or fire suppression system, backflow testing is required to prevent contaminants from entering the municipal water supply.

What Is Backflow & How Does It Happen?

Backflow occurs when water flows in the opposite direction than intended, allowing contaminants to enter the clean water supply. This typically happens when there is:

  • A sudden drop in water pressure (such as a water main break or high demand)
  • Cross-connections between potable and non-potable water sources
  • Improperly installed backflow preventers

A properly installed backflow preventer acts as a barrier, stopping pesticides, chemicals, and waste materials from contaminating your water supply.    

What Happens During a Backflow Test?

During a backflow test, The Waterworks’ certified technicians will:

  1. Shut off the water supply to inspect the backflow prevention device.
  2. Check test cocks and shutoff valves to ensure proper function.
  3. Use specialized pressure gauges to measure differential pressure readings.
  4. Identify leaks, pressure issues, or faulty components.

If any issues are detected, our team can immediately perform the necessary repairs—saving you time and money.

Unlike some companies that only certify devices, The Waterworks provides both testing and repair services in a single visit.

Called JonLe to fix furnace. Thermostat was calling for heat and fan was running, but no combustion. Technician arrived within 2 hr and identified problem as the inducer motor not working. It had seized. He was able to manually get it turning again and lubricated it to get it running. He recommended ordering a replacement because it would likely fail again. I agreed and he returned next day to install the new one. Furnace is working great. Have used JonLe for 20 yr as they installed the furnace when we built our house. Very satisfied with their service plan on my furnace and air conditioner. Happy to recommend them.

We have been using Jonle for 20+ years. Technician (Mark Johnston) performed our annual furnace maintenance this past week. He was on time, courteous and thorough. Once complete, Mark showed us pictures of the inside of our furnace and explained the services he performed, including changing the filter (I provided) and the humidifier pad. Overall we were pleased as always.

We had a great experience with Travis, the Waterworks drain tech that cleared my septic tank clog. My first call to the main number resulted in getting emergency service scheduled, I was texted technician's information and ETA, and the work was done quickly and professionally. Travis made several good proactive recommendations on which I will certainly follow up. I did pay an Overtime charge but it could have been worst overall.

I have had our furnace/heat pump check-ups and service done by JonLe (merged with Tri-County) for over 20 years and counting. From the HVAC installers (2/3 units replaced over these years). I have my summer and winter services BOTH done annually, using your Annual Service Agreement. Many of my services have been performed by Technical Engineer Steve and he has "ALWAYS" done professional jobs. He's great at trouble shooting, explaining and a "GREAT ASSET" to the JonLe Company; great skilled professional people with people skills is always a plus for any Company. I have recommended JonLe to family and friends that have also had great experiences. From Dave, Dennis, etc who installed my latest HVAC unit in recent years unit to Steve you have quality experienced staff. Again, Steve is a GREAT asset to your Company and one reason, I have continued service with JonLe; and recommended your Company to family and friends. Other HVAC services constantly are trying to expand their business with less expensive deals, etc. but I have remained a satisfied loyal customer; feel very comfortable that our HVAC system is always in top condition. I do wish everyone at JonLe a GREAT end of year Holiday's too; stay safe and well!
